Why this rock is probably not a meteorite:
There's no fusion crust. The
outside is stained, but there's no glassy crust.
The interior texture does resemble some lunar meteorite breccias
in that there is a whole range of clast sizes and they're mostly
angular,
not highly rounded. (See NWA
2995) It's suspicious, however, that
all of the gray
"clasts" look the same. Lunar breccias are sometimes called
"polymict" breccias because they're mixtures of different
kinds of rocks.

What is it?
It might be a meteorite; the finder is having a chemical analysis
done.
Alternatively, it might be a terrestrial volcaniclastic rock,
like an ignimbrite, or even a piece on concrete.
